Patent EP-0122795-A1 (EP)
Inventor: WOODWORTH LEE R
IPC: F02B1/04
Filed: 1984-04-13
Abstract: A high-speed rotary filter device comprises a tubular housing (24) containing a bladed rotor (22). The rotor carries inducer blades (30) in a radial outflow configuration, driving blades (32) extending axially above the length of the rotor, and exducer blades (36), and is driven by a shaft at high speed to cause an air stream to be drawn into the housing inlet end (22) by the inducer blades and to travel axially along the housing between the driving blades (32) whilst being forced to swirl around the rotor body (34). 
     Particles suspended in the airstream migrate centrifugally to the internal surface of the housing wall, where they are collected in circumferential grooves (100, 102, 104) and escape from the housing through passages (110, 200, 212) in the housing wall. The filtered air stream is discharged by the exducer blades (36) through the outlet end of the housing via a scroll (50). In a modification (Figure 4) the inducer blades (130) are of axial-flow configuration, and act as a turbine wheel to drive the rotor under a gas pressure differential. In another modification (Figure 7) the inducer blades (172) are of mixed flow configuration. Afurther modification (Figure 14) involves a porous shroud (310) in the form of a helical winding of spaced turns of wire wound around the tips of the rotor driving blades (320) to minimise secondary swirl. In an alternative design (Figure 13) to minimise secondary swirl a rotor (232) having a separator portion (23) with no driving blades is provided. The filter devices are capable of filtering out particles ranging from 2 mm diameter down to 2 microns diameter from a gas stream without clogging, and can also be used for filtering liquids.

Abstract: An apparatus for measuring a gas mass flowing through a pipe per unit of time comprises a constriction (5) into which a pin (6) is inserted which may be moved a greater or lesser distance into the constriction thereby varying the smallest section of the constriction. The constriction is intended for the passage of gas through it at sonic speed. If the area of the sonic section and the nature of gas are known, only the total pressure and temperature will have to be measured in order to enable the mass flow to be calculated. For an accurate measurement of the total pressure and upstream of the constriction the gas should have come to rest. Therefore upstream of the constriction a stilling chamber 7 of relatively large section is disposed and this stilling chamber contains the means (8, 9) for measuring the temperature and pressure. Further the constriction is bounded by a truncated De Laval jet pipe (4).
